Plug Power Inc (PLUG)

[WeTheMarket]

Fish, for private hydrogen fueling stations, as far as I know, Plug Power is the largest (in the US), followed by Nel Hydrogen, for public stations, FirstElement Fuel (Link), and many other companies as you can see at the following link https://hyfindr.com/hydrogen-refueling-station/.

Almost all of public hydrogen refueling stations in the US are in California, see map at following link https://www.energy.ca.gov/data-reports/energy-almanac/zero-emission-vehicle-and-infrastructure-statistics/hydrogen-refueling.
